How to overcome the feelings of insecurities
If we depend on others who are also imperfect, then this usually will not end well. There is a natural tendency to want to love someone. By our spiritual nature we need to experience loving and being loved. Instead of trying to be loved by others, instead of trying to be pleasing to the temporary names and forms of this world, this need must be directed towards the Supreme Person. I must come to appreciate that God loves me and develop my love for God. You are as valuable as the one who is loving and protecting you. The highest self-esteem you can achieve is to realize that I am the loved child of the Supreme owner. You cannot achieve this as long as you are in body consciousness. The eternal spiritual being is glorious and cannot be destroyed. We have eternal value. When we don't know about our real value and worthiness and try to find it through material means, e.g., our body, this is a great cause for the anxieties and insecurities that we experience.
